In the Apple Support article on SMC reset it reads "On MagSafe power adapters, the LED might change states or temporarily turn off when you reset the SMC.". Other than that SMC reset does nothing visible. So probably the reset is working. It seems like the battery is dead. In that case the Mac will throttle the CPU to reduce power consumption. This explains ...

I would recommend restoring the device once and not installing any app for a day to two to recalibrate the battery and diagnose any battery related issues. After that follow the steps given by @Ebe. I normally install an app and check if it decimates my battery before installing another one.

I have uploaded a bash script as a Gist to my Github account at print_osx_uptimes.sh which may help answer your question, even if not exactly what was asked (which was more complicated). The script will query the Apple System Log (ASL) facility for 'shutdown' messages. The 'Message' field’s values contain the system uptime as of the shutdown event, which I ...

I have the same problem on MacBook Pro Retina, early 2013, OSX 10.10.5 Yosemite. Shutting down without warning around 22%. In the battery menu it says "Service the battery". The reset of the SMC didn't help. Yesterday I asked at Genius Bar about this. The answer was "We need to investigate it and probably you will have to replace the battery." It is not free ...

There are two approaches that could lead to less power consumption: a display that is enabled to have a dedicated greyscale mode; less pixels to be in charge of software that automatically renders "less" if you tell it not to render any colors Whilst the first is definitely not applicable as the iPhone features an LCD screen, the latter is something I ...

No, I'm afraid it does not reduce the power consumption of your device. LCD screens (which the iPhones use) use - almost - the same amount of power no matter what colour is being displayed, and the majority of this power is used by the backlight, so if you lower the brightness of the display you can actually save power. As far as I know, the Galaxy Note ...

I had the same problem, apparently my iPad couldn't be any more charged. So I brought it to a shop, and voila, they could charge it. Point being to really really use the original "fat" charger and not another one (like the thin one of an iPhone). The chargers differ in the maximal current they can supply (more than 2A is needed for the iPad).

Sounds like a bad battery, to me. Over time, batteries just wear out to the point of not holding a charge or charging very slowly. An iPad is pretty tough to repair, so unless you have some experience in repairing them, I'd seek a pro to replace the battery for you.

mediaserverd stays at around 1% cpu on my 5s. If it's staying higher, it's most likely an app playing something in the background, perhaps when it shouldn't be.

Unfortunately, there are no ways to disable those alerts unless your device is jailbroken. In that case (device is jailbroken), you can search Cydia for a tweak that disables those alerts.

In the context of the statistics shown here, the 'faults' represent 'page faults', which are actually benign and refer to an attempt to read something that was not present in memory. This is taken care of in the virtual memory system by 'paging' the requested memory into the memory map of the process. But the OS keeps track of how many of these there were. ...

There are a few possible things that could have happened. I've ordered them (and their solutions) below from most to least likely. Explanations: You have a faulty cord. It has become frayed on the inside. One of the metallic connectors is dirty. Dust or dirt has collected in your charging port. Your wall outlet is not functioning correctly. You have a ...

The Wi-Fi antenna in your phone has a typical range of few meters. It finds a Wi-Fi router within that range. So the power of the signal should be enough that it would be able to survive for few meters. On the other hand, for 3G data transfer, you need to send the signals to the receiving antenna which could be a up to a few kilometers from where you are. ...

Here are some tips about the batteries that go inside Apple computers and devices. lithium cells will catch on fire and burn with such intensity that they can ignite almost anything that is combustible if you damage during the replacement. To save space, Apple engineers designed the case of your MacBook to protect the battery - once you open the case, the ...

This is the generally first aid when a device gets wet. TURN IT OFF as fast as possible. Don't even think about turning it on again till you are very sure it is dry. Don't try charging or plugging it in. Water and power do not mix well. While leaving it off and unplugged, stick it in a bag container with dry rice. Rice ascorbs moisture, and if there is ...

If your computer says it's charging but the battery level percentage is still going down, then you're putting way too much stress on it. It's a rare occasion, but I have seen it happen once or twice. If your battery percentage goes up, no matter how slowly, you should still be okay to use it while charging. EDIT: Sorry, I don't know whether or not a ...
